Task 3: Establish shear-wave splitting map of Iceland

Figure 9 shows a map with roundels and equal-area rose diagrams of shear-wave splitting polarizations at stations with more than about ten arrivals within the shear-wave window out to $45^\circ $. Experience suggests that an overall shear-wave splitting map is not particularly useful as was first thought. Optimum procedures seem to require individual studies of shear-wave splitting at individual stations.
